Cold temps, wind, and freeze-thaw cycles define the Butte climate and your deck needs to be built for all of it. We use composite or treated lumber, structural reinforcements, and frost-depth footings that perform through tough Montana seasons. Historic neighborhoods present unique challenges too. We preserve character while improving safety and structure. Whether it’s a rebuild, upgrade, or new install, we get it done strong, safe, and stylish.

How Can We Help?

From porch upgrades to multi-tiered backyard retreats, we build it right the first time.

No matter the property type Victorian on a slope or a ranch-style off Harrison Avenue we tailor your deck to fit. That means smart layouts for elevation changes, custom railings that match older architecture, and material choices that endure Butte’s winters. We’ve built rooftop decks near Uptown, backyard patios in Ramsay, and pergolas with views of Our Lady of the Rockies. Every build balances structural strength with visual harmony.

In Butte, decks face constant freeze-thaw stress, so we use materials that can take the punishment. Composite boards from trusted brands like TimberTech and Trex resist warping and cracking, while cedar offers warmth with proper sealing. All fasteners and supports are selected to withstand corrosion, snow load, and temperature shifts. We help you compare every option and make an informed decision based on where you live and how you use your space.
From permitting with Butte-Silver Bow officials to final inspection, our team manages the entire process so you don’t have to juggle contractors or paperwork. We provide engineered drawings, secure materials, and handle demo, framing, and finishing. Our crews work clean, stay on schedule, and build to the region’s strict safety codes. Whether it’s a ground-level cedar platform or a second-story view deck, we’ve got it covered.


Uptown Butte: Home to some of Montana’s oldest properties, Uptown requires decks that respect historic details while improving safety and structure. We blend new materials with period charm.

Walkerville: With steep lots and exposed terrain, Walkerville demands precise deck engineering and secure foundations. We build with safety and slope in mind.

Ramsay: This rural-feel area calls for outdoor spaces built for views and function. We’ve installed pergolas, covered porches, and multi-tier decks on open properties here.
